The exact founding date of Munsusa Temple is unknown because there are no official records that have been discovered. The temple is estimated to date back to the Goryeo dynasty due to a prayer found in 1973 at the Gilt-bronze Seated Buddha in the temple’s Geungnaksiljeon Hall dated 1346. Around 600 items were discovered along with the prayer, including unbleached ramie cloth, a short-sleeved gown, rice, and barley. Munsunsa has the tranquil atmosphere of a mountain temple. When spring arrives, cherry blossom flowers and wild flowers bloom across the mountain and the nearby cattle farm call to mind a traditional Korean painting.

Munsusa Temple's Geungnaksiljeon Hall is a beautiful building constructed in the Jusimpo style (the column brackets placed only on top of the columns) combined with Dapo style (the column brackets placed between columns as well as on top of the columns). It is designated as Chungcheongnam-do Tangible Cultural Property No. 13. Inside the gorgeously and majestically carved hall are many relics including Gilt-bronze Seated Buddha, Samsebulsang statues (statues of Buddhas of Three Times (past, present and future)), Nahansang statues (statues of disciples of Buddha), and various portraits of Buddha.

The Gilt-bronze Seated Buddha (x_height: 70cm, length between knees: 50cm) was created in 1346. It is a fine example of late Goryo dynasty style Buddha statue along with Gilt-bronze Seated Bhaisajyaguru Buddha of Janggoksa Temple (Treasure No.337).
